The Sun is not on the same plane with the planets
I together with some of my friends have discussed this, and this may be only personal opinion (of my friend and mine); it is not written in the book
The Universe and the Quran and which is not told by the late interpreter; it is only our deduction: it may be right then it is right, and it may be wrong: then it is our mistake.
The deduction came from "the interpretation of the Quran
84: 16-19
فَلَا أُقْسِمُ بِالشَّفَقِ . وَاللَّيْلِ وَمَا وَسَقَ . وَالْقَمَرِ إِذَا اتَّسَقَ . لَتَرْكَبُنَّ طَبَقًا عَن طَبَقٍ
The explanation:
(But no, I swear by the twilight [zone: the zone intermediate between the day zone and the night zone!]
And by the night and [by] all [the beasts] that it will round up!*
And the moon, when it will be at the full!
[That] you [people] shall traverse a plane after another.)
The interpretation:
[* It means: That everlasting night will round up or collect the living creatures; because they will run away from the heat of the day-side.]
When these signs will take place, like the occurrence of the evening-glow and the everlasting night and what beasts it will round up; at that time you will ride up the planes or layers of the atmosphere: a layer after another, so that you will rise up and get nearer to the sun;
i.e. Earth will take you: mounting the layers of the sky: one layer after another."
The earth approaches the sun
From this sentence, it is obvious that the Earth will ascend up the layers of the sky and by doing so, it will get nearer to the Sun.
Our deduction:
It appears from this description and the interpretation of the Quran ayat here, that: the sun is not on the same level as the planets;
i.e. the Sun and the planets are not on the same plane and level:
the Sun is higher than the level of the rest of the planets, and it may be that each planet has its own plane.
As in the drawing that I am giving as attachment to this post.
